Dementia is no longer a far-off disease that affected a select few people, it is now a devastating reality most of us face, whether it due to our daily habits, when we wake up, what we eat and how much pollution we face. Anything and everything we do could change the trajectory of our brain health. However, things are not as bleak, we still have the time to turn things around and take a healthier turn in life and it doesn’t have to be overcomplicated things. A simple change can make all the difference in the world. A new research published in the American Journal of Geriatric Psychiatry looked into Blue Zones—areas where people live longer—has long suggested that having a sense of purpose is linked to a longer life. Now, a new study from UC Davis shows that having a purpose may also help protect the brain from cognitive decline. The study followed over 13,000 adults aged 45 and older for up to 15 years. Researchers found that people who said they had a higher sense of purpose were 28% less likely to develop cognitive issues like mild cognitive impairment and dementia. This protective effect was seen across all racial and ethnic groups and was significant even when accounting for other factors like education, depression, and a gene that is known to increase the risk of Alzheimer's. What Gives Your Life Purpose? The researchers in this study didn't ask people to list what gave their life meaning. However, other studies on aging have shown that many different things can help you find a sense of purpose. The Japanese even have a word for it, "ikigai," which means "a reason for being." Relationships: Spending quality time with loved ones, like caring for family or enjoying time with grandchildren.Work or Volunteering: Continuing to work, mentoring others, or volunteering for a cause you care about. Spirituality or Faith: Participating in spiritual practices or being an active member of a faith-based community.Personal Goals: Taking up new hobbies, learning new skills, or working toward a personal goal, no matter how small.Helping Others: Doing acts of kindness, taking on a caregiving role, or advocating for a cause. Purpose Delays Cognitive Decline The study also found that people with a strong sense of purpose started to experience memory and thinking problems later in life. On average, this delay was about 1.4 months over an eight-year period. While that might not sound like much, it's very significant. Think about it this way, current medications for Alzheimer's can have a similar modest effect, but they often come with risks and are expensive. A sense of purpose, on the other hand, is a completely free, safe, and accessible way to improve your brain health. It's something anyone can work on, no matter their age or background. Study Methods and Why It Matters The people in this study were part of a large national survey. To measure a sense of purpose, researchers used a survey with questions like, "I have a sense of direction and purpose in my life." Although this study showed a clear link between purpose and a healthier brain, it didn't prove that one directly causes the other which means the lack of purpose may not be the cause of dementia. However, the findings strongly suggest that being in a good mental and emotional state is a key part of healthy aging. Even if the socializing with the same people with The researchers are now hoping to find out if programs designed to help people find purpose could actually help prevent dementia in the future.
